Selank vs Semax
Compare Selank and Semax, two Russian-developed nootropic peptides with distinct neurological mechanisms. One excels in anxiolytic research, the other in cognitive enhancement and BDNF upregulation.
Selank
Cognitive / Neuropeptides
Semax

Comparación Lado a Lado
Derived from immunomodulatory tuftsin with Pro-Gly-Pro extension; modulates Th1/Th2 cytokine balance, increases BDNF mRNA in hippocampus, produces anxiolytic effects via GABAergic modulation without sedation
Derived from ACTH(4-10) with Pro-Gly-Pro extension; increases BDNF and TrkB receptor expression, modulates dopaminergic and serotonergic systems, provides neuroprotection, improves cerebral circulation
GABA receptors, enkephalinase, Th1/Th2 cytokine pathways, monoamine systems
BDNF/TrkB pathways, dopaminergic and serotonergic systems, melanocortin-related
~3-5 minutes in serum; functional CNS effects last hours
~3-5 minutes in serum; CNS effects persist for hours
Typically studied 1-3x daily (intranasal or injection)
Typically studied 1-3x daily (intranasal or injection)
Anxiety reduction without sedation, immune modulation via tuftsin pathway, cognitive enhancement and memory, GABA and monoamine system modulation, nootropic pharmacology
